Description

The Custom Shop D-18 brings top-shelf tonewoods and handcrafted Martin quality within easy reach. Built with solid genuine mahogany and an Adirondack spruce top, it delivers clear, punchy tone with powerful projection—perfect for flatpicking, strumming, and everything in between. Hand-shaped Golden Era scalloped forward-shifted bracing and a traditional dovetail neck joint give it vintage-inspired resonance and dynamic response, while faux tortoise binding adds a unique twist on Style 18 tradition. It’s a special addition to our lineup that offers the full Custom Shop experience—no design session required. Whether you’re stepping up to your dream guitar or adding something truly inspiring to your collection, the Custom Shop D-18 proves that high-end craftsmanship doesn’t have to be hard to find.
